java - How to simulate 120 concurrent users of a web application with real conditions? -
how simulate > 120 concurrent users using load test framework such jmeter? real concurrency, far understand, possible if use 120 servers or 120 cpu cores.
how did/do test web application or service real conditions?
i have found jmeter work fine, use across 4-5 pc's accurate results.
although may believe 120 concurrent users may difficult simulate single pc, have realise in real work scenario, 120 simultaneous users not accessing server @ same time, therefore cpu threading algorithms sufficient simulate load.
what need understand usage of application users, i.e. how many requests per second/minute single user , make sure test simulates effectively.
so, our technique use jmeter running on 5 pcs running different tests, , monitor server performance during tests.
there of course many other products available price able better simulate web traffic, have found jmeter needs.
